PCI: cadence: Drop unused member from struct cdns_plat_pcie

The struct cdns_plat_pcie contains a member called is_rc that is not
being used beyond being assigned a value within the cdns_plat_pcie_probe()
function, which is then not used for anything.

Thus, drop is_rc from the struct cdns_plat_pcie, especially since there
already is an is_rc member within the struct cdns_plat_pcie_of_data that
is actively used to convey information about the PCIe controller mode.
